Chapter 4: Multiple Representation
Transcript of Chapter 4: Multiple Representation
and Melanie Chapter 4: Multiple Representation 4.1.7 Multiple Representation There are 4 different ways to represent data: 4.2.1 System of Equation Vocab. The Equal Value Method Rule x => y Table Graph Pattern Ex: y = 5x - 2 Ex: Ex: [ Complete the Reset ] Ex: All are reversible to each other Intersection Point of intersection: Where two or more lines/ curves meet. SIGNIGICANT BECAUSE IT DEPENT ON THE PROBLEM. System of Equation Tile Pattern Two or more lines/ curves used to find a point of intersection Equal Value Method: non-graphing method to find the point of intersection or solution to a system of equations -2x + 5 = x - 1 y = -2x + 5 (2,1) Using y = mx + b form Write Solution in ordered Paired 3 8 13 18 23 28 How will Fig. 4 look like? Graph Rule Table Pattern Goes By a Specific Pattern Area:
Perimeter: 1 1 1 1 1 1 1 1 1 1 1 1 12 Units 1 1 1 1 5 Units^2 1 AREA:
PERIMETER: 17 Units^2 36 Units y-intercept constant growth y-intercept (0,1) growth=
3 Vocab. to Remeber - Tile Pattern Did you see that Graph? That line in the graph there is something unique about it.
It is a straight line. It is called a linear line. - X --> Y table - Graph - Rule - Linear Vocab Alert! - Point of intersection -System of Equation -3x = -6 x = 2 y = -2(2) + 5 y = 1 Final Vocab Alert! - Equal Values Method - Solving an Equation Learning Log- 4.1.2 To figure out the #s in the rule FROM a pattern. We first looked for the growth, and went backwards to Figure 0. So then the rule went to this: Ex. 4-11 y = 2x + 3 FIGURE NUMBER FIGURE 0 CONSTANT
GROWTH Learning Log- 4.1.3 The GROWTH is shown in a rule by being multiplied by the figure number. Y = 5x + 2 GROWTH The Growth is shown in a graph by if its increasing or decreasing Determining which pattern goes faster it should be a graph to see the progress or compared all by a specific figure # Learning Log- 4.1.4 Y = mx + b constant growth Figure 0/ Y-intercept You can see it in each Figure Number because you can substitute "x" for any figure number and it will work. (X , Y )
